WV Violetear: Yes, they do have quite a lot of white to the tail. From above, the white is quite distinct (as broad white tips to the outer rectrices) when the tail is spread out, but rather difficult to see when "closed". From below it is always quite distinct, even when the tail is "closed". From this plumage, they change gradually - but rather rapidly (as is the case with the juv.-ad. transition in most hummingbirds) - into the adult plumage, getting progressively greener below (starting with green flecks on the throat and chest-region) and a progressively smaller malar (a few, probably females, actually retain a trace of a malar when ad.). Photos of somewhat older individuals can be seen here:* <a href="http://www.flickr.com/photos/luthiana/2077205362/" target="_blank">http://www.flickr.com/photos/luthiana/2077205362/</a>* <a href="http://www.flickr.com/photos/samuelbetkowski/3047246276/" target="_blank">http://www.flickr.com/photos/samuelbetkowski/3047246276/</a>* <a href="http://www.flickr.com/photos/pedersoli/3099467906/" target="_blank">http://www.flickr.com/photos/pedersoli/3099467906/</a>* <a href="http://jeffersonotaviano.multiply.com/photos/album/58/Passarinhando_em_Campinas_e_Brotas_-_SP.#4" target="_blank">http://jeffersonotaviano.multiply.com/photos/album/58/Passarinhando_em_Campinas_e_Brotas_-_SP.#4</a>* <a href="http://www.arthurgrosset.com/sabirds/white-ventedvioletear.html" target="_blank">http://www.arthurgrosset.com/sabirds/white-ventedvioletear.html</a> (last photo)Things worth noticing in juv. WT Goldenthroat is the distinctly "dropped" tip of its bill (something found in all goldenthroats, regardless of species & age) with at least base of lower mandible orangish/pinkish (this, however, often require good views, and is far less distinct that the extensive orangish/pinkish of the bill of the ad. male), buffier tone below, complete lack of blue to the tail (but careful; iridescent colours easily confuse), etc. Nevertheless, while I've never really thought about this potential of confusion, it evidently happens with some frequency, as upon checking aves.brasil I found the following placed among the White-vented Violetears:<a href="http://www.aves.brasil.nom.br//files/photos/125/4368/14559.jpg" target="_blank">http://www.aves.brasil.nom.br//files/photos/125/4368/14559.jpg</a></blockquote>
